The coroners hearing in Christchurch into the death of a scientist in Antarctica six years ago has been adjourned indefinitely.
The inquest reconvened on Wednesday morning looking into the circumstances surrounding the death of Australian-born astrophysicist Rodney Marks in May 2000.
The 32-year-old was working at the South Pole station when he died of acute methanol intoxication.
It was earlier revealed he was binge drinker who self-medicated for a mild form of tourettes syndrome.
The inquest had heard testimony from police who have been investigating the matter and a doctor who worked in Antarctica for a number of years.
Much of his evidence was suppressed but police told the court they do not believe the man knowingly ingested the methanol.
